+## Fira Code: la fuente monoespaciada con ligaduras gratuita para programación
+
+![Fira Code](./extras/logo.svg)
+
+Leer en [English](./README.md) | [简体中文](./README_CN.md) | [日本語](./README_JA.md)
+
+### El problema
+
+Los programadores usamos muchos símbolos, frecuentemente codificados con varios caracteres. Para el cerebro humano, sucesiones como `->`, `<=` o `:=` son unidades lógicas individuales, incluso si requieren dos o más caracteres en pantalla. Nuestros ojos utilizan una cantidad no nula de energía para leer, analizar y unir caracteres mútiples en una sola unidad lógica. Idealmente, todos los lenguajes de programación deberían estar diseñados para representar los operadores con símbolos Unicode; pero ese no es el caso aún.
+
+### La solución
+
+Fira Code es una fuente monoespaciada gratuita que contiene ligaduras para combinaciones multicaracter comunes en programación. Esta es simplemente una característica del renderizado de la fuente: el código subyacente permanece compatible con el estándar ASCII. Esto ayuda a leer y comprender más rápido el código. Para algunas sucesiones comunes, como `..` o `//`, las ligaduras nos permiten hacer correcciones en el espaciado.

+
+Fira Code es un proyecto personal desarrollado en mi tiempo libre, sin financiamiento y con una enorme [lista de solicitudes](https://github.com/tonsky/FiraCode/issues). Si el resultado es de tu agrado, por favor considera apoyar a su desarrollo por medio de [GitHub Sponsors](https://github.com/sponsors/tonsky) o [Patreon](https://patreon.com/tonsky). ¡Cualquier ayuda cuenta!
+
+### ¿Qué ofrece?
+
+Izquierda: ligaduras renderizadas en Fira Code. Derecha: las mismas secuencias de caracteres sin ligaduras.
+
+<img src="./extras/ligatures_es.png" width="812" height="1326">
+
+Fira Code viene con una gran variedad de flechas. Mejor aun, ¡estas pueden hacerse tan largas como se desee y se pueden combinar los fragmentos incial/medio/final de la forma que se quiera!
+
+<img src="./extras/arrows_es.png" width="754" height="799">
+
+Fira Code no solo se trata de las ligaduras. Algunos ajustes se han hecho a la puntuación y a pares de letras frecuentes.
+
+<img src="./extras/typographics_es.png" width="754" height="649">
+
+Fira Code viene con algunas variantes de caracteres, de manera que cada uno puede escoger lo que mejor le convenga. [Cómo activar (en inglés)](https://github.com/tonsky/FiraCode/wiki/How-to-enable-stylistic-sets)

+
+Algunas ligaduras pueden alterarse o activarse usando conjuntos estilísticos/variantes de caracteres:
+
+<img src="./extras/ligature_variants_es.png" width="754" height="561">
+
+Siendo una fuente para programación, Fira Code tiene un soporte fantástico para dibujos ASCII/de cajas, powerline y otras formas de interfaz de usuario para terminal:
+
+<img src="./extras/console_es.png" width="754" height="459">
+
+Fira Code es la primera fuente para programación en ofrecer glifos dedicados al dibujo de barras de progreso:

+
+En acción:
+
+<img src="./extras/progress_es.gif" width="594" height="181">
+
+Esperamos que más fuentes adopten esta convención y definan sus propias versiones.
+
+La covertura del estándar Unicode hace de Fira Code una gran elección para la escritura matemática:

+### Compilando Fira Code localmente
+
+En caso que se quiera modificar el código en FiraCode.glyphs y compilar archivos OTF/TTF/WOFF propios, estas son las instrucciones que uso en macOS:
+
+```bash
+# instalar las herramientas requeridas para la compilación
+./script/bootstrap_macos.sh
+
+# compilar los archivos de la fuente
+./script/build.sh
+
+# instalar los OTFs en ~/Library/Fonts
+cp distr/otf/*.otf ~/Library/Fonts
+```
+
+Alternativamnete, se puede compilar Fira Code usando Docker:
+
+```bash
+# instalar las dependencias en un contenedor y compilar los archivos de la fuente
+make
+
+# comprimir los archivos de la fuente en dist/ a un zip
+make package
+```

+Fira Code comes with a few different character variants (`cv01`, `cv02`, etc), stylistic sets (`ss01`, `ss02` , etc) and other font features (`zero`, `onum`, `calt`, etc), so that everyone can choose what’s best for them.

 ### Building Fira Code locally
 
-In case you want to alter FiraCode.glyphs and build OTF/TTF/WOFF files yourself, this is setup I use on macOS:
+In case you want to alter FiraCode.glyphs and build OTF/TTF/WOFF files yourself, this is the setup I use on macOS:
 
 ```bash
 # install all required build tools
-./script/bootstrap
+./script/bootstrap_macos.sh
 
 # build the font files
-./script/build
+./script/build.sh
 
 # install OTFs to ~/Library/Fonts
-./script/install
+cp distr/otf/*.otf ~/Library/Fonts
+```
+
+Alternatively, you can build Fira Code using Docker:
+
+```bash
+# install dependencies in a container and build the font files
+make
+
+# package the font files from dist/ into a zip
+make package
+```
+
+If you want to *permanently enable* certain style sets or character variations, maybe because your editor of choice does not allow you to toggle these individually, you can provide the desired features as a comma separated list to the build script via the `-f / --features` flag.<br>Default: none.
+
+To separate different versions of your font you can specify the desired font family name with the `-n / --family-name` flag. The special value 'features' will append a sorted, space separated list of enabled features to the default family name.<br>Default: "Fira Code"
+
+You can also limit the font weights that will be created with the `-w / --weights` option.<br>Default: "Light,Regular,Retina,Medium,SemiBold,Bold"
+
+```bash
+# locally in your shell
+./script/build.sh --features "ss02,ss08,ss10,cv03,cv07,cv14" --family-name "Fira Code straight" --weights "Regular,Bold"
+
+# or via a docker container (creates the family name 'Fira Code cv01 cv02 cv06 cv31 onum ss01 ss03 ss04 zero')
+docker run --rm -v "${PWD}":/opt tonsky/firacode:latest ./script/build.sh -f "cv01,cv02,cv06,ss01,zero,onum,ss03,ss04,cv31" -n "features"

+## Fira Code: 免费的编程连字等宽字体
+
+![Fira Code](./extras/logo.svg)
+
+### 问题
+
+开发者们使用的多标记，通常都是用几个字符编码。对于人的大脑来说，像`->`、`<=`或`:=`这样的序列是单一的逻辑标记，即使它们在屏幕上显示两到三个字符。您的眼睛并非无消耗的来扫描、解析并将多个字符连接到一个逻辑字符中。理想情况下，所有编程语言都应该为操作符设计成熟的Unicode符号，但现在还不是这样。
+
+### 解决方案
+
+Fira Code是一种免费的等宽字体，包含常用的编程语言中多种字符组合的连字。这只是一个字体呈现功能，底层代码仍然与ASCII兼容。这有助于更快地阅读和理解代码。对于一些常见的序列，如`..`或`//`，连字允许我们纠正间距。
+

+
+### 在本地构建 Fira Code
+
+如果您想更改 FiraCode.glyphs 并自己构建 OTF / TTF / WOFF 文件，这是我在 macOS 上使用的设置：
+
+```bash
+# 安装所有编译需要的工具
+./script/bootstrap_macos.sh
+
+# 编译字体文件
+./script/build.sh
+
+# 将otf文件安装到 ~/Library/Fonts
+cp distr/otf/*.otf ~/Library/Fonts
+```
+
+或者，您可以使用 Docker 构建 Fira Code：
+
+```bash
+# install dependencies in a container and build the font files
+make
+
+# package the font files from dist/ into a zip
+make package
+```
+
+如果你想要*永久开启*某个特定的文体集或者字符变种，但你的编辑器有可能不允许你单独开启它们，你可以将你想要的功能作为一个用逗号分隔的列表，通过 `-f / --features` 标志来加入到编译脚本中。<br>默认：无。
+
+要分隔不同的字体版本的话，你可以用 `-n / --family-name` 标志来指定你所需的字体系列名称。特殊值 'features' 将在默认的系列名称后面添加一个有序的、空格分隔的列表，列表内为已经启用的功能。<br>默认："Fira Code"
+
+你也可以用 `-w / --weights` 选项来限制将要被编译的字体的重量。<br>默认："Light,Regular,Retina,Medium,SemiBold,Bold"
+
+```bash
+# 在你本地的shell中
+./script/build.sh --features "ss02,ss08,ss10,cv03,cv07,cv14" --family-name "Fira Code straight" --weights "Regular,Bold"
+
+# 或者通过一个docker容器 (创建系列名为：'Fira Code cv01 cv02 cv06 cv31 onum ss01 ss03 ss04 zero')
+docker run --rm -v "${PWD}":/opt tonsky/firacode:latest ./script/build.sh -f "cv01,cv02,cv06,ss01,zero,onum,ss03,ss04,cv31" -n "features"
+```

+## Fira Code: プログラミング合字のフリー等幅フォント
+
+![Fira Code](./extras/logo.svg)
+
+[English](./README.md) | [Español](./LEEME.md) | [简体中文](./README_CN.md) で読む
+
+### 問題点
+
+プログラマは多くの記号を使用し、しばしば数文字で符号化されます。人間の脳にとって`->`、`<=`、`:=`といったシーケンスは、たとえ画面上で 2 文字や 3 文字になったとしても、単一の論理トークンである。あなたの目は、複数の文字をスキャンし、解析し、1 つの論理的なものに結合するために、ゼロではない量のエネルギーを費やしているのです。理想を言えば、すべてのプログラミング言語が演算子のための本格的なユニコード記号を備えて設計されるべきですが、まだそうではありません。
+
+### 解決法
+
+Fira Code は、一般的なプログラミングの複数文字の組み合わせのための合字を含む無料の等幅フォントです。これは単にフォントのレンダリング機能であり、基礎となるコードは ASCII 互換のままです。これによりコードをより速く読み、理解することができます。`...` や `//` のような頻度の高い文字列は、合字によって間隔を修正することができます。
+
+### ダウンロードとインストール

+### Fira Code をローカルでビルドする
+
+FiraCode.glyphs を変更し、OTF/TTF/WOFF ファイルを自分でビルドしたい場合、私が macOS で使用している設定は次のとおりです:
+
+```bash
+# 必要なビルドツールをすべてインストール
+./script/bootstrap_macos.sh
+
+# フォントファイルのビルド
+./script/build.sh
+
+# OTF を ~/Library/Fonts にインストール
+cp distr/otf/*.otf ~/Library/Fonts
+```
+
+または、Docker を使用して Fira Code を構築することもできます:
+
+```bash
+# コンテナ内に依存関係をインストールし、フォントファイルをビルド
+make
+
+# dist/ のフォントファイルを zip にまとめる
+make package
+```
+
+特定のスタイルセットやキャラクタバリエーションを *永久的に* 有効にしたい場合、おそらくあなたの選んだエディタではこれらを個別に切り替えることができないため、`-f / --features` フラグでビルドスクリプトにカンマ区切りリストとして希望の機能を提供することができます。<br>デフォルト: なし。
+
+異なるバージョンのフォントを分けるために、`-n / --family-name` フラグで希望のフォントファミリー名を指定することができます。特別な値 'features' を指定すると、有効な機能をソートしてスペースで区切ったリストをデフォルトのファミリー名に追加します。<br>デフォルト: "Fira Code"
+
+また、`-w / --weights` オプションで、作成されるフォントのウェイトを制限することができます。<br>デフォルト: "Light,Regular,Retina,Medium,SemiBold,Bold"
+
+```bash
+# ローカルでシェル内
+./script/build.sh --features "ss02,ss08,ss10,cv03,cv07,cv14" --family-name "Fira Code straight" --weights "Regular,Bold"
+
+# または Docker コンテナ経由（ファミリー名 'Fira Code cv01 cv02 cv06 cv31 onum ss01 ss03 ss04 zero' を作成）
+docker run --rm -v "${PWD}":/opt tonsky/firacode:latest ./script/build.sh -f "cv01,cv02,cv06,ss01,zero,onum,ss03,ss04,cv31" -n "features"
+
+# Git for Windows の Git Bash やその他の MSYS2 ベースのシェルで使用する場合は、パス変換を無効にする必要があるかもしれません
+MSYS2_ARG_CONV_EXCL="*" docker run --rm -v "${PWD}":/opt tonsky/firacode:latest ./script/build.sh -f "ss02,ss03,ss04,ss05,ss06,ss07"

+FreeBSD
+-------
+
+Using pkg(8):

+
+
+Enabling ligatures
+==================
+
+Atom
+----
+
+To change your font to Fira Code, open Atom's preferences (`cmd + ,` on a Mac, `ctrl + ,` on PC), make sure the "Settings" tab is selected, or the "Editor" in Atom 1.10+, and scroll down to "Editor Settings". In the "Font Family" field, enter `Fira Code`.
+
+If you wish to specify a font weight, for example, Light, use `Fira Code Light` as a font name (Windows) or `FiraCode-Light` (macOS).
+
+Ligatures are enabled by default in Atom 1.9 and above.
+
+
+VS Code
+-------
+
+To open the settings editor, first from the File menu choose Preferences, Settings or use keyboard shortcut `Ctrl + ,` (Windows) or `Cmd + ,` (macOS).
+
+To enable FiraCode in the settings editor, under "Commonly Used", expand the "Text Editor" settings and then click on "Font". In the "Font Family" input box type `Fira Code`, replacing any content. Tick the check box "Enables/Disables font ligatures" under "Font Ligatures" to enable the special ligatures.
+
+If you wish to specify a font weight, for example, Light, use `Fira Code Light` as a font name (Windows) or `FiraCode-Light` (macOS).
+
+
+IntelliJ products
+-----------------
+
+1. Enable in Settings → Editor → Font → Enable Font Ligatures
+2. Select `Fira Code` as "Primary font" under Settings → Editor → Font
+
+Additionally, if a Color Scheme is selected:
+
+3. Enable in Settings → Editor → Color Scheme → Color Scheme Font → Enable Font Ligatures
+4. Select Fira Code as "Primary font" under Settings → Editor → Color Scheme → Color Scheme Font
+
+
+BBEdit
+------
+
+1. Install FiraCode as per the [macOS installation instructions](https://github.com/tonsky/FiraCode/wiki/Installing#macos)
+2. Open BBEdit preferences, Editor Defaults, assign Fira Code as the Default font
+
+
+Brackets
+--------
+
+1. From the `View` menu choose `Themes....`
+2. Paste `'Fira Code'`, at the beginning of `Font Family`
+
+
+Emacs
+-----
+
+There are a few options when it comes down to using ligatures in
+Emacs. They are listed in order of preferred to less-preferred. Pick one!
+
+1. Using composition mode in Emacs Mac port
+
+If you're using the latest Mac port of Emacs (https://bitbucket.org/mituharu/emacs-mac by Mitsuharu Yamamoto) for macOS, you can use:
+
+    (mac-auto-operator-composition-mode)
+
+This is generally the easiest solution, but can only be used on macOS.
+
+2. Using prettify-symbols
+
+These instructions are pieced together by https://github.com/Triavanicus, taking some pieces from https://github.com/minad/hasklig-mode.
+
+This method requires you to install the Fira Code Symbol font, made by https://github.com/siegebell:

+3. Using composition char table
+
+Thanks to https://github.com/seanfarley for putting this together; extended by https://github.com/jrblevin.
+
+Put this lisp in your .emacs:
+
+    (when (window-system)
+      (set-frame-font "Fira Code"))
+    (let ((alist '((33 . ".\\(?:\\(?:==\\|!!\\)\\|[!=]\\)")
+                   (35 . ".\\(?:###\\|##\\|_(\\|[#(?[_{]\\)")
+                   (36 . ".\\(?:>\\)")
+                   (37 . ".\\(?:\\(?:%%\\)\\|%\\)")
+                   (38 . ".\\(?:\\(?:&&\\)\\|&\\)")
+                   (42 . ".\\(?:\\(?:\\*\\*/\\)\\|\\(?:\\*[*/]\\)\\|[*/>]\\)")
+                   (43 . ".\\(?:\\(?:\\+\\+\\)\\|[+>]\\)")
+                   (45 . ".\\(?:\\(?:-[>-]\\|<<\\|>>\\)\\|[<>}~-]\\)")
+                   (46 . ".\\(?:\\(?:\\.[.<]\\)\\|[.=-]\\)")
+                   (47 . ".\\(?:\\(?:\\*\\*\\|//\\|==\\)\\|[*/=>]\\)")
+                   (48 . ".\\(?:x[a-zA-Z]\\)")
+                   (58 . ".\\(?:::\\|[:=]\\)")
+                   (59 . ".\\(?:;;\\|;\\)")
+                   (60 . ".\\(?:\\(?:!--\\)\\|\\(?:~~\\|->\\|\\$>\\|\\*>\\|\\+>\\|--\\|<[<=-]\\|=[<=>]\\||>\\)\\|[*$+~/<=>|-]\\)")
+                   (61 . ".\\(?:\\(?:/=\\|:=\\|<<\\|=[=>]\\|>>\\)\\|[<=>~]\\)")
+                   (62 . ".\\(?:\\(?:=>\\|>[=>-]\\)\\|[=>-]\\)")
+                   (63 . ".\\(?:\\(\\?\\?\\)\\|[:=?]\\)")
+                   (91 . ".\\(?:]\\)")
+                   (92 . ".\\(?:\\(?:\\\\\\\\\\)\\|\\\\\\)")
+                   (94 . ".\\(?:=\\)")
+                   (119 . ".\\(?:ww\\)")
+                   (123 . ".\\(?:-\\)")
+                   (124 . ".\\(?:\\(?:|[=|]\\)\\|[=>|]\\)")
+                   (126 . ".\\(?:~>\\|~~\\|[>=@~-]\\)")

+                              `([,(cdr char-regexp) 0 font-shape-gstring]))))
+
+**Note!** If you get `error in process filter: Attempt to shape unibyte text`, check out https://github.com/tonsky/FiraCode/issues/42. Emacs Cider users may avoid this issue by commenting the following line from the above config:
+
+    ;; (46 . ".\\(?:\\(?:\\.[.<]\\)\\|[.=-]\\)")
+
+Char `45` is also known to have issues in macOS Mojave.
+
+If you are having problems with helm you can disable ligatures in helm:
+
+    (add-hook 'helm-major-mode-hook
+           (lambda ()
+             (setq auto-composition-mode nil)))
+
+4. Using font-lock keywords
+
+If none of the above worked, you can try this method.

+    ;; This works when using emacs without server/client
+    (set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol")

+    }
+
+4. Click Apply or OK
+5. Happy coding!
+
+
+Cloud9
+------
+
+In a workspace:
+
+1. Click Cloud9, then Preferences (or use keyboard shortcut CTRL + ,)
+2. Go to Themes, then click on You can also style Cloud9 by editing your stylesheet (this will open a blank styles.css file in the C9 editor)
+3. Copy & paste the following:
+
+    @font-face{
+        font-family: 'Fira Code';
+        src: url('https://raw.githubusercontent.com/tonsky/FiraCode/master/distr/eot/FiraCode-Regular.eot') format('embedded-opentype'),
+             url('https://raw.githubusercontent.com/tonsky/FiraCode/master/distr/woff2/FiraCode-Regular.woff2') format('woff2'),
+             url('https://raw.githubusercontent.com/tonsky/FiraCode/master/distr/woff/FiraCode-Regular.woff') format('woff'),
+             url('https://raw.githubusercontent.com/tonsky/FiraCode/master/distr/ttf/FiraCode-Regular.ttf') format('truetype');
+        font-weight: normal;
+        font-style: normal;
+    }
+
+    .ace_editor{
+        -webkit-font-feature-settings: "liga" on, "calt" on;
+        -webkit-font-smoothing: antialiased;
+        text-rendering: optimizeLegibility;
+        font-family: 'Fira Code';
+    }
+
+4. Back in Preferences tab, click on User Settings, then click on Code Editor (Ace)
+5. In Font Family field, enter Fira Code
+6. Optionally, repeat step 5 for Preferences > User Settings > Terminal, if you want Fira Code font in C9 terminal.
+
+
+MacVim
+------
+
+Add this to ~/.gvimrc:
+
+    set macligatures
+    set guifont=Fira\ Code:h12
+
+MacVim supports ligatures starting from version 7.4.
+
+
+RStudio
+-------
+
+In RStudio:
+
+1. Go to Tools > Global Options > Appearance
+2. Select "Fira Code" as Editor Font. In older versions of RStudio, check "Use Ligatures".
+3. Hit "OK" and enjoy
+
+
+Sublime Text
+------------
+
+Preferences --> Settings
+
+Add before "ignored_packages":
+
+    "font_face": "Fira Code",
+    "font_options": ["subpixel_antialias"],
+
+If you want enable antialias, add in font_options: "gray_antialias"
+
+
+Visual Studio
+-------------
+
+1. Launch Visual Studio (2015 or later).
+2. Launch the Options dialog by opening the "Tools" menu and selecting "Options". 
+3. In the Options dialog, under the "Environment" category, you'll find "Fonts and Colors". Click on that. You'll see a combo-box on the right hand side of the dialog labelled "Font". Select "Fira Code" from that combo-box. 
+4. Click "OK" to dismiss.
+5. Restart Visual Studio.
+
+Now, most FiraCode ligatures will work. A notable exception is the hyphen-based ligatures (e.g. the C++ dereference '->'). See https://github.com/tonsky/FiraCode/issues/422 for details.
